**** Prerequisites **** 
This replication archive requires an R installation with the following libraries (and their dependencies):
  Main document: MSCMT, parallel, readstata13, BMisc
  Appendices (add.): sandwich, lmtest, car, multcomp, arm



**** Instructions ****
We supply a Makefile. If you have the make utility installed (standard on most Linux installations; part of the Command Line Tools on MacOS [run xcode-select --install in a terminal]), you can reproduce all tables and figures by simply invoking --make main-- (for the main document) and --make appdx-- (for the complete online appendix). All code is written in R.

The Makefile (and the comments therein) also serve as reference linking R code to tables and figures. 



**** Included files ****
Datasets:    CountryEPData_covIP.dta, CountryEPData.dta. See __Codebook.pdf__ for variables and sources.
.R files:    run models, create plots
.Rnw files:  create tables

We also include generated outputs from all model runs (.pdf files for figures;  .tex files for tables).
